I went to the Chopin series last year and it was the best concert experience I had ever had. The pianist was awesome and even played my favourite polonaise as the end. The theatre is very cozy and there is a theatre bar for drinks before and after and during the intermission. It is a great place, and in a great location in the center of Guadalajara. I came back this year to go to the new season of classics but ALL the tickets were sold out for the whole month. Book early!
